| Abstract | ||||
| The anti-salinity effects of six substances—arginine, mannitol, proline, salicylic acid, seaweed extracts, or potassium silicate—each at 500 ppm—were assessed over the 2021 and 2022 seasons. Keitte mango trees were treated with three spray treatments of either of these substances: at the beginning of growth, after fruit setting, and one month later. The trees were grown in soil and irrigation water with salinity levels of 4.51 dsm and 3.03 dsm, respectively. The trees' growth, productivity, and fruit quality were observed, as well as their nutritional condition. In comparison to salinity stress alone, adding any of the six materials: mannitol, proline, salicylic acid, seaweed extracts, or potassium silicate (500 ppm) to the trees improved growth characteristics, tree nutritional condition, yield, and fruit quality. The best substances for minimizing the salinity-induced negative effects were, in ascending order, arginine, mannitol, proline, salicylic acid, seaweed extract, and potassium silicate. Exposing the Keitte mango trees to any of the six studied materials resulted in an improvement in growth aspects, the nutritional status of the trees, yield, and fruit quality when compared to trees that were grown under the stress of salinity alone. The most effective materials, ranked in ascending order in terms of their ability to alleviate the negative effects of salinity, were arginine, mannitol, proline, salicylic acid, seaweed extract, and potassium silicate. To counteract the unfavorable impact of soil and water salinity on the growth and fruiting of Keitte mango trees, it is suggested to spray potassium silicate or seaweed extracts (500 ppm) three times: at the beginning of growth, immediately after fruit setting, and one month later. | ||||
